Be it known that I, FRANK O. BALOGH, a citizen of the United States, residing at Lakewood, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Envelopes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The general purpose of this invention is to provide an envelope which shall be capable of being readily opened, after the contents are sealed therein, without the use of a paper knife or similar instrument. In carrying out my invention, I provide an envelope such as the usual mailing envelope, with a' weakened portion along which the envelope may be readily severed or torn. I

prefer to arrange this weakened portion transversely across the envelope, whereby the body of the envelope may remain intact after opening. Y

. A further object of my invention is to so shape the line ofv weakening as td leave inwardly projecting flaps or tabs adapted to be gripped between the thumb and finger, whereby they may be pressed against the contents of the envelope and as a. 'pull is given to remove the end'of the envelope, thereby opening the same, the contents of the envelope are simultaneously withdrawn.

My invention is hereinafter illustrated in the accompanying drawings, showing a preferred embodiment thereof, and the following description is intended to .make clearv the above and other features of this invention as relates to the embodiment shown. The essential characteristics are summarized in the claim. ,Y

In the drawings Fig.' 1 is an elevation of the front of an envelope, provided with the weakened portion and specially arranged tabs constituting-my invention; Fig. 2- is a view showing t e envelope as opened, with the contents being removed with the piece of theV envelope at the end severed and carrying with it the con-tents;Fig. 3 illustratesv a slightly modified form of the invention,

with a view to giving the perforated portion an artistic effect, Fig. 4 is in the nature 'of a section or detailv through the severed portion, showing the manner in which it embraces the contents. v

Describing my invention more fully with theuse of characters of reference, A indicates an envelope suchas is usually used for Y an ornate design.

tab or flap 10.y It will be understood that these perforations or' slits 5, 6 and 7 extend through both the front and back of the envelope. The tabs 10 are preferably only partially severed from'the body of the envelope. The drawings show one connection, but obviously the lines 7 may be simply continuations of the weakened portions.

Assuming nowV that the envelope has been sealed, and it s desired to open the same,

Athe tabs 10 are grasped between the thumb and finger of one hand, while the body of the envelope is held preferably adjacent the opposite end by the other hand, and by merely drawing outwardly while holding the tabs 10 firmly, the end portion designated B of the envelope`-is torn from the body thereof along the lines 5, 6 and 7, and the continued movement carries with it the contents of the envelope designated C, as illustrated particularly in Figs. 2 and 4.

The modification illustrated in Fig. 3 is identical in principle, but the lines 5, 6, and the slits 7 are curved somewhat, as may be desired by the designer, to aord It will be seen that the shape of the weakened lines may be varied at will, and it is to be understood that they may beformed by a series of slits or scormgs, or by otherwise treating the paper to weaken it, whereby it affords sufficient strength to retain the contents, at the same time ermitting the ready removal of the enc osure- Eby the velo e removed by the tearing along the wea ened lines, whereby the contents are simultaneously withdrawn.
